Area Forecast Discussion
National Weather Service Billings MT
305 AM MDT TUE MAY 31 2016

.SHORT TERM...valid for Tdy and Wed...

Little in the way of changes for the short term forecast this
morning. The upper level low has shifted off to the
northeast...bringing wrap around showers to the area. Best chances
for precipitation will be east of Billings...but shower activity
is possible across the region. Showers will exit into the Dakotas
by sunset. The bigger concern today is increasing northwest
winds across the region. The pressure gradient will continue to
increase through this morning...with strongest winds in west and
central zones are expected by late morning...and decreasing
through the day. Gusty winds in the east will continue through
the afternoon, with gusts of 40 to 50 mph. Winds will taper off
during the early evening. Additionally, temps will be cool across
the area, with highs in the low to mid 60s.

Clear skies and dry air point to much cooler night, but developing
upper level ridge of high pressure will limit cool off somewhat,
with low in the 30s and 40s across the region tonight. Dry
conditions will continue for Wednesday as ridge axis moves over
the region. Daytime highs will climb quickly above normal...with
highs near 80 degrees over central and eastern zones. Eastern
zones will be cooler...but still see highs above 70 degrees.

.LONG TERM...valid for Thu...Fri...Sat...Sun...Mon...

Only significant change to the extended was to add a slight chance
of showers and thunderstorms for Thursday afternoon/evening as
models drag the tail end of a canadian shortwave through the area
along with a weak cold front. Otherwise models remain consistent
with zonal downslope flow Thursday, transitioning to northwesterly
flow Friday as West Coast ridge amplifies. Tempted to add some low
pops in for Friday as well given northwest flow aloft and some
weak energy but so far models hinting against this so held off for
now. Ridge builds into the area from the west for the weekend
into early next week. Outside of low precipitation chances
Thursday and maybe Friday the rest of the period looks pretty
dry, with low diurnal mountain pops each afternoon. Temperatures
look to push into the 80s Thursday and stay there through early
next week, with the potential there for a 90 degree day late
weekend or early next week. Chambers



Scattered showers will prevail east of a Billings to Sheridan line
today into early this evening. Periods of MVFR ceilings with this
activity including the KMLS TAF site. Otherwise VFR conditions
will prevail. West to Northwest winds of 30 to 40kts can be
expected across the area from early this morning through sunset
this evening. The strongest winds will occur from Rosebud county
east. Chambers
